3.0 Connecting to the
Chimney
Masonry Chimney
When installing a Jøtul F
100
into a masonry chimney
through a “thimble” (the opening through the chimney
wall to the flue), the thimble must consist of ceramic tile
or steel and be securely cemented in place.
The chimney connector/stove pipe must slide completely
inside the thimble to the inner surface or the flue liner.
It may be necessary to make use of a thimble sleeve (a
pipe with a slightly smaller diameter than standard stove
pipe).
See figure 6
.
The connector pipe or thimble sleeve must not protrude
into the flue liner or otherwise restrict draft.
Use refractory cement to seal the seam between the
chimney connector, sleeve, and thimble.
Do not connect this stove to a chimney flue servicing
another appliance of any kind.
Hearthmount into a Masonry Fireplace
The Jøtul F
100
may be installed into a masonry
fireplace with a minimum opening height of 22 1/2”
(572 mm).
Building code requires that the fireplace damper plate be
removed or securely fixed in the open position. A connector
pipe must then extend from the stove’s flue exit through
the damper area of the fireplace and into the chimney tile
liner.
See figure 7
.
The inside area of the flue liner must not be less than the
area of the stove flue collar and cannot be more than three
times greater than the cross sectional area of the stove
flue collar.
If the chimney liner is too large to accommodate the stove,
an approved relining system must be installed to resize
the flue.
A new sheet metal damper block-off plate must be installed
around the connector pipe at the damper frame and sealed
with the proper sealant (usually High-Temp Silicone).
